Gunderic

Gunderic (318-363) was the king of the Frisii after the death of his father King Adalwolf in battle. Gunderic was killed in the Siege of Campus Frisii (which his father tried to lift) in 363 by the Saxons.

Biography
Gunderic was a pagan Frisian who lacked any command, management, or influence, while his father Adalwolf had a small grasp on the skills of command. Gunderic commanded the Frisian garrison of Campus Frisii in present-day Holland, and fought a 363 AD siege by Saxons. Gunderic was killed in battle shortly after his father was, dying when the Saxons assaulted the city in winter 363.
